I've read a few posts where the inner tube on Happijac camper jacks have fallen out when it's supposed to be retracted. Here is my version of a retention cable to prevent this.

I found these "Nite Ize S-Biner" S hooks at Home Depot. They're made of stainless steel and have a spring clip attached:

I drilled (countersunk slightly to prevent fraying), primed, and painted the jack support bracket:

After cutting the cable to length and removing the insulation I swaged on a Nicopress sleeve. Heat shrink tubing was added inside the loop to prevent wear:

Here's a close up of the cable loop and stainless S-Biner:

When the jacks are raised I simply clip the cable onto one of the holes in the jack foot and run the jack down a little bit to take up the slack. Now all I need to do is remember to remove the cable before I lower the jacks![emoticon] Later, Dave.

Excellent Idea. I have never had a problem but always worried about it. One less thing to worry about.

Great Idea, but I'm also curious about your rear folding step. Is it of the folding multi-step type (motorhome style). Looks like it is attached directly to the rear bumper. Could you provide a picture?

Thanks

Does this happen only on the 4600 model jacks or all models? The reason I ask is the 4600 have the release to drop the jacks down all the way in a matter of seconds as apposed to waiting for the motor to bring them down.


Happy TC'N,
David

Here are a couple that the dealer took before I purchased:

The steps are folded up together, then they both pivot out and down, then the bottom step rotates off of the middle step and down, and yes it is attached directly to the bumper.

I'm not sure. I just remember reading a few posts about this subject. A couple of other members have done similar mods. Later, Dave.

Thanks, for the rear picture. So is this a retrofitted step I take it, or an original equipment item from the TC builder?

Hey great idea!

But man, where is the rust on your jacks? I thought everybody has rust on their jacks. I do, and I've de-rusted them once already. Must be that Georgia "dry" climate, eh?[emoticon]

I had them install it at the dealer in Denver before we bought it. At the time it was an option that came with the rear bumper. I'll see if I can get a better picture posted for you.

What is this "rust" you speak of? I'm also confused about "winterizing" I've seen bantered about on the forum. Can anyone give me some clarification on these words?[emoticon] Later, Dave.

What was the problem, specifically? The jack falling out? How does that happen? That does not sound good, especially while under way.

Looks like I have a new project...thanks Dave!
